Abstract: A multi-purpose tracheal tube for use with high frequency ventilation. The tube is an endotracheal tube including up to three lumens, in addition to the primary lumen, which serve various functions to provide versatility in the treatment of patients. In cuffed tubes one of the lumens is used for inflating the cuff once the tube has been placed in the desired position in the trachea of the patient. Another lumen, referred to as the "insufflation lumen", is used to deliver oxygen or other gases by constant insufflation, intermittent jet ventilation or high frequency ventilation. The third lumen, when incorporated, is employed for monitoring and irrigation. The distal opening of the irrigation or monitoring lumen is located just inside the distal tip of the tube while the insufflation lumen opening is located rearwardly toward the proximal end of the tube relative to the irrigation or monitoring lumen opening.

Abstract: In a deinking process for a fibre stock or slurry air is introduced into the slurry so that air bubbles and ink come into contact, and the ink-laden bubbles are then separated from the slurry. 
<??>In order to provide an improved separation process the invention proposes to independently control the air injection, the mixing of the air and slurry, and the separation process by splitting them into separate steps so as to optimise the separation process. 
<??>Thus, there is provided a separation cell (31) which is fed with slurry from an inlet, an air inlet device, which in one embodiment comprises a porous sintered sleeve (7) to which air pressure is applied, and a mixing section which imposes turbulent flow on the air bubbles and slurry by passing the constituents through a series of turbulence discs (39). The resulting mixture enters the separation cell where the ink-laden bubbles rise to the surface as a foam which is conveniently removed by suction. The reinked slurry being drawn off from the separation cell.
